The Monster's Ball beauty held hands with French hunk Martinez as they posed for pictures at the Carousel of Hope event in Beverly Hills, making their first official outing since becoming romantically involved while filming Dark Tide in South Africa over the summer (10).
An eyewitness tells UsMagazine.com the stars were "inseparable" at the bash, while Unfaithful actor Martinez was "constantly leaning in and whispering in Halle's ear, making her laugh".
And the couple appears to be getting serious - Berry reportedly introduced Martinez to her mother, Judith, earlier this month (Oct10).
Berry split from model Gabriel Aubry, the father of her daughter, in April (10). Martinez previously dated pop star Kylie Minogue.
